Objective Gingival recession is a complication that can occur after orthodontic treatment, and its cause is still very controversial in the literature. The objective of this study was to report a clinical case of orthodontic retreatment conducted with in‐office aligners and root coverage using free gingival graft, connective tissue graft, and Emdogaim for a patient with severe gingival recession. Clinical Considerations This report presents a potential solution to correct a gingival recession with in‐office clear aligner. A mandibular left lateral incisor whose root was positioned buccally to the bone plate, likely due to improper bonding of a fractured orthodontic retainer. The treatment consisted of 10 in‐office aligners, which effectively repositioned the root within the alveolus. After the orthodontic retreatment, the patient underwent gingival grafting surgery, which was successful due to the accurate positioning of the root in the socket, influencing bone deposition in the area. Subsequent 4‐year follow‐up showed treatment stability, mainly in the soft tissue area. Conclusion Within the limitations of this case report, the in‐office aligners facilitated individualized and precise movements, allowing for torque adjustments when necessary. Besides that, the improved root positioning facilitated successful surgical procedures for covering the gingival recession, including the free gingival graft (FGG) and connective tissue graft with Emdogain (CTG + Emdogain). Clinical Significance This case report presents an orthodontic treatment alternative for the multidisciplinary correction of a gingival recession, meeting the esthetic and functional demands of an adult patient.

The etiology of malocclusions includes a number of endogenous or exogenous factors, intrinsic or extrinsic factors, and genetic or environmental factors. Among the potential environmental causes are cysts or tumors,4,5 of which radicular cysts are the most common (42.9%), followed by dentigerous (also known as follicular) cysts (39%).

Objective To evaluate the knowledge and preference of patients treated at a Dental School in Jaraguá do Sul, Brazil, about using aligners and the reasons for choosing this device as a treatment option. Design A cross-sectional study. Participants A total of 82 participants aged 18–45 years recruited at a screening clinic. Methods A questionnaire was completed in person using a tablet with digital forms. Results Almost half of the participants (49%) knew about aligners; 40% were aged 18–24 years, and 77% were female. When observing the images of the types of orthodontic appliances, the aligners had an acceptance rate of 80%. Among the reasons that led to the preference for choosing aligners, 68% cited aesthetics and 42% comfort. Conclusion Recently, clear aligners have become a popular choice for orthodontic treatment, particularly among adults. Despite their popularity and effectiveness, many patients still need more information about aligner treatment. Over half of the respondents did not know what orthodontic aligners were. Younger participants had more knowledge about aligners than older participants. Patients still need more knowledge about the types of appliances available for orthodontic treatment. When presented with images of the kinds of devices available, almost 80% of participants showed greater satisfaction with aligners.

Objective To compare the anterior crowding correction after sequential use of the first 5 aligners between two aligner exchange protocols (7 and 14 days) in mature adult patients. Materials and Methods Thirty‐six patients over 35 years who received orthodontic treatment with Invisalign® were randomly allocated to two different aligner replacement sequence protocols: Group 1: exchange every 7 days (n = 18); and Group 2: exchange every 14 days (n = 18). All patients were scanned with iTero Element 5D® (Align Technology) in two treatment times: at pre‐treatment (T1) and after using the first five aligners (T2). Little's Irregularity Index (LII) and arch widths were evaluated with OrthoCAD software. Intra and intergroup comparisons were performed with the dependent and independent t ‐tests. The results were considered significant for P < .05. Results Thirty‐five patients completed the study. Both groups' maxillary and mandibular Irregularity Indexesi were significantly lower at T2. There was no significant difference in inter‐canine, inter‐premolar, and intermolar distances. G2 (14 days) presented a greater decrease in mandibular irregularity than G1 (7 days). Conclusion Both exchange protocols (7 and 14 days) effectively correct anterior crowding in the initial phase of orthodontic treatment with aligners in mature adult patients. However, the 14‐day exchange protocol provided a greater correction in mandibular anterior crowding in the evaluated period than the 7‐day exchange protocol.
